Question

65.A small bob A of mass M is attached at one end of a massless string of length L which is fixed at one end O. The bob is released from the given initial position as shown in the fig. the time period of oscillations will be 1. pi/2 [ sqrt L/g)] 2. pi [sqrt(L/g)] 3. 3( pi/2) {sqrt(L/g)] 4. 2 pi [sqrt(L/g)]
